v Zia/6221 57 PHILIP F. WALGER, OF CHICAGO, ILLINOIS.

AWNING.

Application filed June 10, 1916.

To all whom it may concern:

Be it known that I, PHILIP F. WALGER, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Awnings, of which the following is a specification.

The present invention is an improvement upon the awning of the type shown in Letters Patent No. 801,121 granted October 10, 1905, to Philip T'Valger and lVilli am l Yalger.

The principal object of the present invention is to provide improved means for locking or fasteningthe awning in its lowered position to the end that it will not be disturbed or displaced by wind currents.

Tn mild weather the simple weight of the parts will be sufficient to hold them where they belong, but in severe weather something more is required.

In the patent above mentioned a rack bar is jointed to the window frame and this rack bar is engaged by an arm which is also jointed to the window frame and takes the form of a long pawl. This construction is open to many objections that are apparent to those skilled in the art and which need not be here specifically set forth.

In awnings of the class under consideration it is essential that the curtain of the awning be held taut, especially in severe or stormy weather, and to do this is the principal object of the present invention. This I do by the means hereinafter described with reference to the accompanying drawing, in which:

Figure l is a vertical section of a window and of one of the improved awnings applied thereto, the parts being shown, by full lines in the positions which they occupy when the awning is down.

Fig. 2 is a detail view showing the relations of some of the parts in the positions which they occupy when the awning is dropped to its lowermost position in readiness for being raised to its uppermost position, out of use.

In the drawing, 1, represents the window frame or casing, with the construction of which the present invention has nothing, whatever, to do. It may be of any desired construction, since the invention relates to the awning and not to the window construction. However, to the outside of this window frame above the sash are attached Specification of Letters Patent.

brackets, 2, only one of which is shown in the drawing, which brackets support the roller, 3, having at one end a spool, 1, around which is rove a cord, 5, in such manner that by pulling upon the cord the roller will be revolved and the awning, 6, wlll be wound up upon it in a manner which is thoroughly familiar to those skilled in the art. This cord, 5, passes downward to the bottom, or thereabout, of the frame and passes through a sleeve or gromet, 7, so that its lower end, 8, is accessible from the interior of the window. A belaying cleat, 9, is attached to the interior of the window frame, 1, so that when the awning is at the desired position the end, 8, of the cord, 5, may be securely anchored to this belaying cleat. The object of this will appear hereinafter. As in the patent aforesaid the awning, 6, 1s engaged by a rod, 10, which is supported by brackets, 11, located, preferably, about the mid-height of the window, but this location, manifestly, is immaterial. The brackets, 11, may be either higher or lower than the mid-height of the window, accordlng to the discretion of the builder. However, from the roller, 3, to the rod, 10, the awning, 6, extends practically vertical and from the rod, 10, it diver 'es outward and embraces a rod, 12, which is carried at the outer ends of arms 13, the inner ends of which are jointed at 1 1 to sleeves 15 mounted upon vertical rods 16 which are attached by any suitable means to the window frame so as to be incapable of any movement relatively thereto. As shown in the drawing these rods 16 are attached to the window frame as shown at 17, but the means of attaching them is immaterial so far as the present invention is concerned.

Other elements of the device are toggle arms or members 18 the inner ends of which are jointed as at 19 to sleeves 20 fitting and adapted to slide upon the rods 16. These toggle arms have longitudinal slots 21 through which pass studs or pins 22 carried by the arms 13 and these slots have laterally disposed notches 23 which provide shoulders for engaging the pins 22 when the awning is dropped to its lowermost position as shown in Fig. 2.

lVith the parts thus constructed and proport-ioned approximately as shown in the drawing, it is manifest that a downward pull upon the cord, 5, with the parts in the positions shown in Fig. 1, the angular relations of the arms, 13, and the toggle arms, 18, will be such that a pull upon the cord, 5, will tend to lock the parts in the positions shown in Fig. 1. This being so by drawing the cord, 5, downward and anchoring it to the belaying cleat, 9, it is manifest that the parts will be securely held in position, storm proof.

When it is desired to raise the awning the cord must be released from the belaying cleat, 9, so as to allow the awning to fall to the position shown in Fig. 2. When in this position the angle formed by the arms, 13 and 18, will be such that when the cord, 5, is again drawn down, producing a tension upon the awning, 6, the sleeves, 20, will easily slide up upon the rods, 16, so that the parts may be brought to the positions indicated by dotted lines in Fig. l.

The arms, 13, and rod, 12, form a threesided frame which holds the lower end or margin of the awning sheet out from the window frame and in proper relative position thereto, so that when the toggle arm, 18, occupies a sufliciently abrupt angle to the rod, 16, no amount of upward pull upon the awning sheet, 6, or upon the pull cord,

5, can disturb the position of the frame 12-43. v

It will be understood that for the most part the elements described are duplicated on opposite sides of the window frame, the only exception to this duplication being the winding spool, 4, and the pull cord,

hat I claim as new is:

In an awning the combination with an awning sheet of a frame to which the lower margin of the awning sheet is attached a vertically movable slide located above the inner side of the frame, means carried by the window frame for guiding said slide, bracing arms the inner ends of which are pivoted to said slides, said bracing arms having longitudinal slots and lateral notches, providing shoulders, and pins carried by the frame and adapted to enter said notches when the frame is in its lowermost position and whereby when the frame is moved upward said shoulders will engage them and cause the bracing arms to move upward, endwise.
